I don't know if these are the same key caps that came on the magicforce board that dropped recently, but if they are those keys are rather awful to type on. The issue that I have with them is the stem is a rectangle that fits pretty perfectly into the switch and that works just fine if you're pressing your keys straight down every key stroke. I personally do not perfectly press mine down and this creates a sticking feeling where I feel the switch is stuck on the side of the switch and when you don't get it stuck the added friction between the switch and stem is not ideal.
Bottom line is they look cool, but are terrible to type on.
